CanDID: Can-Do Decentralized Identity with Legacy Compatibility, Sybil-Resistance, and Accountability


Wednesday 13B

Convener: Deepak Maram, Harjasleen Malvai

Notes-taker(s):


Tags for the session - technology discussed/ideas considered:

Legacy-compatibility, key management, bootstrapping, sybil-resistance, privacy


Discussion notes, key understandings, outstanding questions, observations, and, if appropriate to this discussion: action items, next steps:


A lot of the discussion focused on our previous work, DECO, which we use as a building block in CanDID. DECO allows a client to prove statements about a TLS session in zero-knowledge, using only cryptographic trust assumptions. Another solution is to use TownCrier, which allows the same functionality, using trusted hardware.


Overall, we showed that various problems get swept under the rug in most identity systems, including bootstrapping, key-management, Sybil-resistance and privacy-preserving and decentralized mechanisms for regulatory compliance. We also show various mechanisms for solving each of these problems.
